During Level B decontamination, it is crucial to perform technical decontamination just prior to SCBA (Self-Contained Breathing Apparatus) removal. Technical decontamination involves the systematic cleaning of personnel and equipment to reduce contamination to safe levels.

This step is essential because SCBA removal without proper decontamination can expose the wearer to hazardous materials that may still be present on their gear. By conducting technical decontamination right before removing the SCBA, the risk of inhalation or dermal exposure to harmful substances is minimized. It typically includes rinsing off contaminants and ensuring that both the protective gear and the individual are clean enough to safely transition to the next steps, such as removal of the SCBA.

The other options serve different purposes. Emergency medical assessments focus on evaluating the health status of individuals who may have been exposed to hazards but do not address the immediate need to decontaminate before equipment removal. Safety briefings are important for ensuring all team members are aware of procedures and risks but are not a direct action taken immediately before SCBA removal. Final inspection of equipment is essential for ensuring everything is functioning correctly post-decontamination, but it occurs after the safety concerns of potential contamination are addressed through technical decontamination.
